For most teenagers a Play Station 2, iPod or the latest clothes would be at the top of their wish list.

But all 13-year-old Connor Knapton wanted was a helping hand in his battle to control the crippling side effects of a brain tumour.

And now, thanks to the staff at the University of Wales Institute, Cardiff, and a generous Welsh company he has got it - in the form of a new exercise bike.

'It is really cool and it means I can now train at home,' said the St Teilos Church in Wales High School pupil, who lives in Springwood, Llanederyn, Cardiff.

The tumour, which Connor has had for most of his life, sits at the centre of his brain and prevents his body from producing any hormones.

His weight has rocketed as a result and the testosterone injections he has now started receiving are making the problem worse. Doctors told his mum Sian Knapton, who has three other sons, Mishak , 10, Kaya , 15, and 26-year-old Denton, that it was crucial he started exercising.

Uwic were able to offer Connor the use of their gym facilities on Saturday and Sunday, but it soon became clear that if Connor was going to achieve his goal of maintaining his weight, he would also have to train at home.

'Uwic's fitness manager Dai Watts knew we wanted a bike for Connor to train on at home and was planning a sponsored event to raise funds to buy it,' said Sian.

'But when he rang the company which makes them, Hiorns International of St Nicholas, Cardiff, to ask how much they were, they said he could have it for free.

'I couldn't believe it when I heard and I think it's just brilliant because you're not just talking about any bike, you're talking about the Rolls Royce of exercise bikes! It's nice to know people are willing to help sick children.'
